Sonoff MINI-RBS Wi-Fi + Matter Relay Module for blinds

Sonoff MINI-RBS smart roller blind module - Matter compatible controller for motorised blinds

Sonoff MINI-RBS is ideal for users who want to upgrade their existing motorised roller blinds or shades with smart functions. It allows bi-directional operation (up/down), step-by-step adjustments and percentage position control. Its compact size (33 x 39.5 x 16.8 mm) makes it easy to install behind wall switches or in distribution boxes. It supports different types of shades - ideal for curtains, blinds, awnings or even motorised home cinema screens. When managing blinds, the module helps to maintain optimum light and temperature conditions, for example by dimming blinds in the summer heat. Thanks to the calibration function, users can precisely adjust the position of the shades in percentage.

A special feature of this module is its compact design - fits into standard 80 mm EU wall brackets. The Sonoff MINI-RBS is significantly smaller than the previous Sonoff Dual R3 module, making it easier to install behind wall switches.

The mini module supports Wi-Fi + Bluetooth and is not only compatible with the Sonoff eWeLink app, but also integrates seamlessly with platforms such as Apple HomeKit, Google Home, Alexa and Home Assistant via Smart Home Standard Matter, allowing compatibility with almost any smart home ecosystem.

When used with eWeLink and the cloud, the module also includes a built-in eWeLink-Remote (Bluetooth) a gateway to connect to wireless R5 switches (available in white and grey) and S-MATE2 module. This allows control of wired pushbutton switches and wireless devices.
